Perfect as a space divider, on either side of a headboard, or simply as a whimsical art installation, the Abacus 6-Light Ceiling-to-Floor LED Pendant features six blown glass globes. With adjustable height cables, the Abacus can be customized to suit any space. True to its namesake, the Abacus globes can be moved up and down their low-voltage cable "rails" by virtue of tiny grippers on each side, to customize each globe's position, with small, solid steel balls anchoring each cable.
